water hammer
Posted by Jan Vrooman on April 11, 2002 at 09:27:51:
When my submersible well pump shuts off, the supply pipe from the well shakes the 3/4" supply line which runs through a crawl space from the well to the pressure tank located in the basement. The total length of the 3/4" supply line from the pump in the well to the pressure tank is about 70'. I maintain about 50PSI pressure, and the air pressure in the tank is about 40PSI. I don't have any water hammer in the house after the pressure tank. The 3/4" schedule 40 PVC supply pipe is hung from the floor joists in the crawl space with plastic loop hangers. Suggestions?
